Product Description
SST11CP22 is a 50Ω, RF-matched Power Amplifier
Module (PAM) with a FCC-compliant, harmonic filter
that is based on the highly-reliable InGaP/GaAs HBT
technology.
Operating over the 5.1–5.9 GHz frequency band,
SST11CP22 meets 802.11a spectrum mask require-
ments up to 24 dBm and 802.11n HT40 spectrum mask
at 23 dBm. With 802.11a modulation, this PA typically
provides up to 20.5 dBm with 3% EVM, and provides
18 dBM with less than 1.8% dynamic EVM using
802.11ac modulation, MCS9, 80 MHz bandwidth.
This power amplifier module also features easy board-level
operation, with a simple application circuit requiring only four
external components. With its high-speed power-up/-down
control, SST11CP22 is controllable directly from the base-
band chip.
SST11CP22 also features a wide dynamic-range, linear
power detector that is temperature-stable and VSWR-
insensitive.
SST11CP22 is offered in 20-contact QFN package. See
Figure 2-1 for pin assignments and Table 2-1 for pin
descriptions.
